LOUIS C. KRUMMEL, 0F CLINTON, CONNECTICUT, ASSIGNOR TO CONTINENTAL MACHINE COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

MULTIPLE DOUBLE-SEAMER.

Application filed December 30, 1909.

To all whom it may concern:

Be it known that I, LOUIS C. KRUMMEL, a citizen of the United States, residing at Clinton, in the county of Middlesex, State of Connecticut, have invented certain new and useful Improvements in Multiple I)Olll)l-SHIDGIS, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

The invention relates to new and useful improvements in multiple double seamers, wherein a plurality of double-seaming mechanisms operate continuously and one after the other on can bodies, for the purpose of attaching an end to the can body.

An object of the invention is to provide a machine wherein a plurality of double seaming mechanisms are brought one after the other beneath a feeding device for feed ing can bodies and can ends to said doubleseaming mechanisms.

A further object of the invention is to provide a device wherein a plurality of double-seaming mechanisms are continuously operated, receiving a can body and can end at one side of the machine, which end is attached to the can body by the double-seaming mechanism during the rotation of the machine, and which can body with the end attached thereto is discharged from the machine at a different point in its rotation.

A further object of the invention is to provide a plurality of double-seaming mechanisms which are simultaneously carried bodily about a supporting shaft, and in which the seaming rolls of the double-seaming mechanisms are operated by stationary cams during the travel of the double-seaming mechanisms.

A further object of the invention is to provide a carrier or body rest which receives the can body and holds the same until it is properly chucked and ready for rotation in the seaming head, which carrier afterward withdraws so as to allow the can body to be rotated.

A further object of the invention is to provide a device for double-seaming, in which the can body and end are rotated in contact with the seaming rolls, by means of a rotating chuck, and by means of a 1'0- Specification of Letters Patent.

Patented Aug. 24%, 31915.

Serial No. 535,680.

tatable supporting plate which engages the opposite end of the can body.

A still further object of the invention is to provide a multiple double-seaming device with a chute for feeding can bodies to the double-seaming mechanisms, together with a support moving with the double-seaming mechanisms, which automatically holds the can bodies .in the chute, and allows the same to drop one at a time into the double-seaming mechanisms; and also to provide automatic means for feeding can ends one at a time to a double-seaming mechanism.

These and other objects will in partbe obvious, and will in part be hereinafter more fully described.

In carrying out my invention, 1 have provided .a supporting frame in which are mounted the various parts of my multiple double-seaming mechanism. Said supporting framework consists of a bed plate 1 from which rise

brackets

2, 2, which brackets carry a stationary shaft 3 extending horizontally through the machine. The parts of my double-seaming mechanism are supported so as to rotate about the stationary shaft 3, and, as herein shown, I have provided four independent doubleseaming mechanisms, or stations which are located substantially 90 apart. Each of said double-seaming mechanisms includes a body rest or carrier 5, which engages the can body and also the can end, when it is fed into the double-seaming station or mechaporting plate 6 engages the end of the can body, which is not to be closed and forces the can body on to the can end, and the can end on to the chuck 7 as clearly shown in Fig. '35. The carrier, after the can body and can end have been properly engaged by the chuck and supporting plate, is moved away from the can body, so that the can end and body mav be rotated by the chuck 7.

The curling roll 8 is moved into engagement with the flange on the can end and can body, and performs the usual rolling of the flange, soas'to form the double seam, The flattening roll 9 is then brought into engagement with the seam and the same compressed and finished. The can bodies are fed to the double-seaming mechanisms by means of an inclined conveyer or chute 10.

- Said chute is mounted on a bracket arm 11,

secured to the bed plate 1 of the machine in any desired way. Said chute is preferably arranged so as to extend at an angle of sub stantially 45 to the vertical.

The chute, as clearly shown in Figs. 5, 6 and 7,.consists of an angle bar 12, which is adjustablycarried by the bracket arm 11. A plate 13' is spaced from the angle bar 12 by a spacing block 14, and said spacing block is of sulficient height so as to form a groove or recess which receives the flange on the end of the can body. A second angle iron 15 supports the opposite end of the can body, and a plate 16- is spaced from the angle iron 15 by a spacing block 17, similar to the spacing block 14. The can ends are also fed through the conveyer or chute 10.

A plate 18 is spaced from the plate 16 by a spacing block 19, and the can ends roll along and24, which are separated by suitable spacing blocksand so disposed as to form re-' cesses or pockets which receive the upper portion of the flange on the can body and the.

upper edge of the can end.

The plates22, 23 and 24 are secured to the standard 21 by a bolt 25. The bolt 25 extends through a slot 26- in the standard. The standard at its upper end is deflected laterally, and through the lateral extension 27 is a threaded bolt 28, which is 'rotatably connected at its lower end to an outwardly extending flange 29, carried by the plate 24.

It will be obvious that upon loosening the bolt 25 the bolt 28 may be adjusted and the plates 22, 23 and 24 moved toward or away from the

plates

15, 16 and 18. 1 The purpose of this adjustment is to enlarge the chute for different size can bodies and can ends. By connecting the plates together, theadjustment may be quickly made as all of the plates are simultaneously adjusted and retain their proper relation to one another.

The can bodies roll freely down the chute or conveyer, and if a seaming station is opposite the end of the chute, the can body will dropinto the seaming station on to the body rest or support 5. If, however, the seaming station is not opposite the conveyer 10, then the segment 30 will receive the can body and serve as a support for the same until the seaming station is brought opposite the conveyer 10. The can ends, however, are held in the conveyor, and automatically released one by 'one. by means of a dog 31, which is pivoted to the plate 18 at 32. The dog 31 normally extends into the path of the can end, and holds the same in the chute or eonveyer. A second dog 33 is also pivot ed to the plate 18, and extends into the path of the can end. A short arm 3% is connected to the dog 31, and extends in a direction toward the conveyer. A short arm 35 is connected with the dog 33 and extends in a direction substantially parallel with the arm 3 and away from the conveyer. A link 36 connects the arms 34 and It will readily be seen that if the dog 33 be oscillated so as to move out of thepath of the can end, the dog 31 will be moved in the opposite direction and into the path of the next can end, so that when one can end is released, the next succeeding can end is caught by the dog 31 and held until the dog 31 is thrown out of the path of the can end, at which time the dog 33 is then again thrown to such position as to engage and hold the can end released by the dog 31.

As a means for operating the dogs 31 and 33. I have provided a rock lever 37 which carries a roller 38 located in the path of travel of the supporting segments 30. A spring 39 engages the outer end of the rock lever, and normally holds the roller 38 pressed against the support 30. A link 40 connects the outer end of the rock lever 37 with the arm 35 of the dog 33. After the plate 30 passes the roller 38, the spring 39 will operate to oscillate the rock lever, and throw the dog 33.

The tripping mechanism for the can ends is located on the under side of the chute. 'hen the segment 30 on one side of the seaming mechanism, passes the roll 38, said dog 33 will be thrown into the path of the can end, and the dog 31 released, allowing the can end to drop on to the dog 33. As soon as the end of the adjacent segment or support 30 engages the roller 38, the dog 33 will be thrown out of the path of the can end and allow the same to drop into the seaming mechanism on to the support 5.

The support or body rest 5 is formed with &

arms 40 which are arranged at an angle to each other, so as to engage the can body at points at one side of the lower portion of the can body. The object of constructing the rest forthe can body with arms disposed as above noted, is for the purpose of providing a body rest, which will receive and properly support can bodies of difierent sizes, as indicated in dotted lines in Fig. 24:. The supporting

arms

40, 40, as clearly shown in Fig. 24, have spaced magnetized steel ribs 41, on which the can body rests, and a wider magnetized steel rib 42. which is of slightly less height than the ribs 41, which receives the can end. These magnetic supports for the can body and can end, prevent the same from re-bounding when they drop from the chute on to the body rest, and hold the can body and can end in proper alinement with the chuck and rotatable supporting plate. Instead of a permanent magnet. it is obvious that an electro-magnet may be used.

The body rest 5 is mounted on a standard 43, which extends into a sleeve 41, and is secured therein by a pin 45. which extends through an opening in the sleeve. and a corresponding opening in the stem 43. 'I have provided the stem 43 with a plurality of openings. and by withdrawing the pin 425, the standard may be adjusted in the sleeve, so as to properly locate the body support for can bodies of different diameters.

The sleeve 44 slides vertically in a supporting bearing 46. mounted on the end of a stem -17. which is carried by a bracket mounted to rotate with the machine. At its lower end. the sleeve 44 carries a. roller 43. The roller 43 is adapted to travel on a cam 49. (see Figs. 1. and 2(5). The cam 4 is held stationary. and is so constructed that the body support is raised to receive the can body just before the seaming station reaches the conveyer 10. and said body support remains raised until the can chuck and supporting plate have engaged the can body and are in position for rotating the same. The body support then drops. as shown diagramn'iaticallv in Fig. 35. so as to allow the can body to be freely rotated. This movement of the body rest moves the magnet out of contact with the can body and allows the free discharge of the cans from the machine. The body rest for the can will drop by gravity away from the can body. as soon as the roller 48 passes off from the raised portion of the cam 4 In order. however. to cause the bodv rest to drop with certainty, I have provided a spring 5 which is attached at to the supporting plate 116.

As a means for rotating the can l)()( y and can end, in order to perform the doubleseaming operation, I have provided the rotating chuck 7 which is mounted on the end of a chuck spindle 50, (see Figs. 1, 14 and 1 one end to the body rest. and at its other end carries abushing 67, which is held in the carrier or by a sleeve through the body and 15). The chuck spindle 50 extends through a split bushing 51, which is secured to the bracket 52. Said carrieris split at its outer end, and provided with clamping bolts 53,-which serve to clamp the bushing tightly in the carrier. Threaded collars 54 and 55 are screwed on to the spindle and hold the same in place and prevent the thrust of the chuck from longitudinally moving the spindle in the carrier or sup' porting bracket. The chuck is secured in any desired way on the end of the chuck spindle. The chuck spindle is rotated by a gear wheel 56, driven in a manner hereinafter described. The carrier or bracket 52 for the chuck spindle, also has a socket 57, which receives the stem 47, supporting the bearing for the body support. Said carrier 52 is bolted to spaced arms 58, (see Figs. 4 and 13). The radial arms 58 are carried 59 (see Figs. 1 and 18), which sleeve 59 is rotatably mounted on the fixed shaft or axle 3 of the machine.

The carriers 52 mounted on the radial arms 58, which as above noted, are carried by the sleeve 59, engage a gear ring 60, (see Fig. 4). Said gear ring is provided with a half threaded socket, 60 which is adapted to register. with a similar half threaded socket 60 formed in the carriers 52, and threaded bolts 61 engaging the two half. sockets serve to hold the gear ring-on the carriers 52. The gear ring 60 cotiperates with a gear- 61 mounted on the main shaft 62, which in turn-is mounted in hearings in the bed-plate 1 of the machine. The main shaft 62 carries the ordinary friction clutch 63 at its outer end. Upon the rotation of the main shaft, the gear 61* will in turn impart a rotating movement to the gear ring, which carriers 52 and radial arms 58 will rotate the sleeve 59 on the stationary axle 3.

The sleeve 59 carries a. bracket disk 64, near. its opposite end, which bracket disk, is splinedto' the sleeve, so asto rotate therewith and move longitudinally of the sleeve. Threaded nuts or collars 65 engage the bracket disk 64, on each side thereof, and

hold-the'same in its adjusted position on the sleeve 59. The sleeve 59 is threaded to cooperate with the nuts or collars 65. The bracket disk 64 is provided with bearings, which are in line with the spindles of the rotating chucks, and a sliding bar 66is located in each bearing (see Figs. 1 and 16) The sliding bar 66 is centrally bored and bar by a suitable set screw 68. A spindle 69 is carried by the bushing 67 and at its outer endsupports a plate 70, which is adapted to engage the open end of the can support the same while it. is being rotated by the rotary chuck. Said plate sleeve 70 is secured to the disk 71, which in turn is threaded on the end of the spindle 69. The spindle 69 carries an enlarged head 72 at its inner end, which holds the spindle in its hearing. A wearing block 73 may be provided to take up the thrust and wear of the spindle 69.

The plate 70 is adapted to fit the inner face of the can body. The disk 71 has a short neck, on which is mounted an ejecting plate 74. Springs 75 are located between the disk 71 and ejecting plate 74, and normally hold said ejecting plate forced outward against the supporting plate 70. Said ejecting plate has a peripheral flange 76, which fits the outer surface of the supporting plate 70.

The sliding bar 66 carries a roller 77 at its opposite end, which runs in a cam groove 78, formed in a cam disk 79. The cam disk 79 has a socket 80, which receives a stud 81, which stud projects from the disk 79 through a suitable opening in the standard 2 of the frame, and operates to hold the cam disk 7 9fr0m rotating with the sleeve 59. The cam disk 79 is mounted on thehub of the bracket disk 64, and the collar 65 holds the same in place. a

After the can'body is fed on to. the body support or rest 5, the bar 66 is moved forward by means of the cam groove 7 8, as the sleeve 59 rotates, and the plate 70, together with the stripper plate 74, engages the open end of the can body and moves the same longitudinally, so that the can body is forced on to the can end and the can end forced on to the rotating chuck 7, so that the can.

body and can end are then rotated by the chuck, the plates 70 and 74 rotating with the can body and chuck.

As above noted, as soon as the can body and can end are properly placed on the chuck, the body rest 5 is lowered from contact with. the can body.

The curling roll 8 is mounted in a carrier 82, which is pivotally carried by a stud 83 -mounted in the socket 84 formed in the bracket or carrier 52 (see Figs. 11, 12 and 13). The stud 83 may be secured in the socket 84 by a set screw or any other similar means. The carrier 82 has a laterally projecting arm 85, in which is mounted a roll 86, which runs on a cam 87 mounted on the 59, and held from rotation, (see Figs. 1, 25 and 26). The cam 87 is so constructed that as soon as the can body and can end are properly seated on the chuck, and are rotated thereby, the curling roll is moved into contact with the flange of the canend and can body, and the double seam formed.

In order that the seaming roll 8 maybe adjusted to vary the pressureof the seaming roll on the flange of the can author for thepurpose of engaging the can ends ofdifier- Litters ent diameters, I have mounted the seaming roll 8 on short spaced arms 88, which are pivoted at 89 in a recess formed in the carrier 82.

The bolt 90 is provided with an eye, which extends between the arm 88, and is secured thereto by a. stud 91. The bolt 90 extends through a threaded sleeve 92, which is carried by a threaded socket in the carrier 82. Said carrier at its outer end is split and provided with a clamping bolt 93. The threaded sleeve 92 has its end formed so as to receive a wrench, so that said sleeve may be adjusted in its supporting socket after the clamping screw 93 has been released. When the sleeve is properly adjusted, the clamping bolt 93 serves to lock the parts in adjusted positions. The bolt 90 carries a nut 91 at its outer end, which holds the same in the adjustable sleeve 92.

The flattening roll 9 is mounted on a carrier 95, which is pivotally supported by a stud, 96, mounted 1n the socket 97 formed in the carrier 52, (see Fig. 13). The stud 96 may be secured in the socket 97 by a suitable set screw or any other similar means. The carrier 95 is. provided with a roller 98, which coiiperates with the cam 99 mounted on the sleeve 59 and held from rotation therewith. The cam 99 is so constructed that the flattening roll is brought into contact With the seam at about the time the curling roll finishes its. operations, and said flattening roll leaves the seam so that the can may be discharged from the machine when thecan body reaches the lower side of the machine.

The flattening roll 9 is mounted between short spaced arms 100, which are pivoted in the recess in the carrier 95 on a short stud 101. A bolt 102 extends through a threaded adjustable sleeve 103, and has an eye 104, which is located between the spaced arms 100 and secured thereto by a pivot stud 105.. The carrier 95 is split at its outer end, and has a clamping bolt 108. The threaded sleeve 103 is formed at its outer end with a nut 107, whereby said sleeve may be adjusted upon the loosening of the clamping bolt 106. The bolt 102 carries threaded nuts 108, which engage the threaded sleeve 103, and limit the movement of the bolt 102.

It is often desirable to provide a yielding means for supporting the flattening roll, so that the same may yield slightly when pass ing a side seam or some other irregularity in the seam being formed. In order to provide a yielding support for the flattening roll, 1 have surrounded the belt 102 with a yielding collar 109, which may be of rubber or the like. When the pressure becomes too great on the flattening roll, the rubber collar 109 will yield, allowing the roller to move away from the seam being flattened. When it is desired to adjust the tension of the flatten ing roll on the seam, this mav be accomplished by adjusting the position of the threaded sleeve 103.

It is often desirable to adjust the osition of the seaming rolls for different sizes of can bodies, and this is accomplished by means of removable washers 111. The bolts 90 and 102 are slightly flattened adjacent the eyes, and the washers 111 are cut away at 112, (see Fig. 10), so said washers may he slipped over the flattened end of the bolts.

In order to hold the washers 111 in place, I have provided a .pin or key 113, which passes through the washer and through the bolts 90 or 102. By removing the washer 111, and substituting washers of different sizes therefor, the position of the seaming rolls 8 and 9 relative to the respectively operating

rollers

86 and 98, may be readily varied.

The cams 87 and 99 are splined to a sleeve 114, which carries the cam 49 for operating the body support. The sleeve 114 is secured to an arm 115, (see Figs. 2, 21 and The arm 115 extends through a slot in the bracket arm 11, and is secured thereto-in any desirable way. The arm 115 will hold the sleeve 11% from rotating with the main sleeve 59, on which it is mounted. As the seaming rolls travel around with the sleeve 59, the operating rollers for the seaming rolls will engage the various parts of the stationary cams, and the seaming rolls will be operated.

A supporting plate 116, .(see Fig. 19) is bolted on the outer end of the supporting bearing for the body support (see Fig. 1), and rotates therewith about the stationary axle 3. Said supporting plate 116 carries the supporting segments 30.

After the can end has been attached to the can body, the. sliding bar 66 is withdrawn by reason of the shape of the cam 78, and the stripper plate 76 will be forced out ward by the springs 75, pushing the open end of the can off from the supporting plate 0. In order to strip the can end from the chuck, I have provided an ejecting pad 117 which is carried by an ejecting rod extending through the chuck spindle. Said ejecting rod carries a collar 118, at its outer end and a spring 119 interposed between the chuck spindle and the collar, normally holds the ejecting pad housed within the chuck.

Said rod has a hardened projection 120 which is adapted to engage a cam 121 (see Fig. 1) carried by the frame of the machine, when the can body reaches the position in the machine where it is to be discharged therefrom. This cam 121 will force the ejecting rod and ejecting pad inward, thus forcing the can end ofl from the chuck. As soon as the ejecting rod passes the cam 121, the spring will return it to normal position.

After-the can end is attached to the can body, and is discharged from the seaming mechanism in the manner above stated, said can body drops into a chute 122, and is carried from the machine. A guard plate 123 extends from the chute 122, and serves to catch the can body if it is dropped from the machine before the seaming station reaches the discharge chute, and the rotating parts will carry the can body along and discharge the same through the discharge chute.

In Figs. 30 to 33, inclusive, I have shown diagrammatically the position of the seaming rolls relative to the can end for the various positions of the can body in its travel through the machine. \Vhen the can end and can body are received from the conveyer on to the body rest, the seaming rolls are both withdrawn, so that the can body and can end may be properly placed on the chuck. When the can body reaches the position indicated at A, (Fig. 2,) the curling roll is in the position shown diagrammatically in Fig. 30; that is, the curling roll is moved into contact with the flanges on the can end and the can body, and the flattening roll is still held away from the can end. When the can body in its travel reaches the position indicated at B then the curling roll has performed its peration, as shown diagrammatically in Fig. 31, and the flattening roll is moving into operative position. When the can body in its travel reaches the position indicated at C (Fig. 2) then the seaming rolls have the position indicated digrammaticalfy in Fig. 32; that is,

the flattening roll is finishing its operation,

and the curling roll has moved away from the can end and can body. -\Vhen the can body in its travel reaches the position to be discharged from the machine, then the seaming rolls are in the position indicated diagrammatically in Fig. 33; that is, both rolls are away from the can end and the can body, so that said can body may be dropped from the machine.

The chucks are rotated by means of a common gear 123, which engages each one of the chuck gears 56. The gear 123 is carried by a hub 124 mounted on a reduced portion of the axle 3. The gear 125 is keyed to the hub 124, and in turn meshes with the gear 126, splined on the main shaft. It will be readily seen that the train of gears operating the chucks will greatly multiply the speed of the driving shaft, so that said chucks will be driven at a much higher rate than the sleeve carrying the seaming mechanisms.

In order to protect the operator from the gears for driving the chuck and the seaming mechanism, I have provided a shield 127,

which is mounted on the frame of the machine and extends over the gears and houses the same. i

It will be .noted from the above description, that I have provided a machine wherein there is a carrier which has a plurality of seaming mechanisms or stations which operate independently of one another. The carrier is continuously rotated, receiving the can bodies and can ends while in motion, and the can ends are secured to the can bodies also while the carrier is in motion, and the cans with the ends secured thereto are discharged from said carrier. The carrier consists of the sleeve which is rotated from the main shaft and the bracket arms and bracket disk which support the chuck, the supporting plate cooperating with. the chuck, the carriers for the seaming rolls and the bearing for the body rest. Said carrier is rotated as above noted, by a gear carried by the main shaft.

By using washers of a predetermined thickness, I am able to adjust very quickly the position of the seaming rolls relative to the chuck so that said rolls are adjusted for operation upon difl'erent sizes of can bodies. I also secure a like adjustment of both the curling roll and the flattening roll.

By adjusting the sleeves through which the bolts for the pivoted arms supporting the seaming rolls pass, I am able to secure an independent adjustment of the curling roll or the flattening roll relative to the carrier on which it is mounted.

It will be obvious that minor changes may be made in the details of construction, and the arrangement of parts, without departing from the spirit of my invention.
